We tested this unit and it works perfectly. The motor purrs and no problems were found. We usually don’t work with pumps but this one was so clean we had to try it out. It pumped a 2 liter Pyrex bottle empty of water in no time at all. For the price we are asking this is a very good deal.
Note: Suction feet a bit shot but pump still works great.
